Well, and whenever capitalist countries enslave 2/3rd of the worlds in colonies (even having "human zoos"), it's not "true capitalism".

>Also, always comes from people who don't/didn't live there

You'd be surprised. E.g.:

"Since communist nostalgia is a growing phenomenon in Eastern Europe today, it has different ways of manifesting itself amongst post-communist citizens. Nostalgic types are quite particular in their reverence for the past and share different things they are nostalgic about (this is shown in their electoral support for communist and socialist parties). Most of these individuals are nostalgic for job security, free education and reliable and affordable healthcare. This is because most Eastern Europeans remember and long for the vast social programmes and services that are no longer offered under capitalism."

"The poll showed 30 percent of Ukrainians approved of the change to democracy in 2009, down from 72 percent in 1991. In Bulgaria and Lithuania the slide was to just over half the population from nearer three-quarters in 1991."

I don’t know of any countries that have adopted “true” communism. Mostly because it’s just easier to seize control of a command economy than figuring out a way to share power.
